My invention relates in general to roof coverings and has particularreference to a so-called composition roofing of that type which isusually furnished in the form of shingles, shingle strips or the like.

The primary object of my invention is to provide roof covering of theabove mentioned type, which may be economically manufactured andconveniently applied to a roof without the aid of special tools or thecustomary nailing devices, as'heretofore more or less commonly employed.

In the accompanying drawing I have shown several illustrativeembodiments of the invention, which for the most part are directed toshingles and shingle, strips.

In said drawing Figure 1 is a plan view of an ordinary rectangularshingle, which fairly well represents the way that these shingles arenow offered to the trade.

' Referring now to the drawing in detail. 5

represents an ordinary form of composition shingle. In one embodiment ofmy invention I take the shingle 5 and turn back two of the cornersthereof to provide interlocking tabs 6. These tabs, when-the shinglesare laid upon the roof, are adapted to either engage diagonal slots 7 ina foundation member 8 (see Fig. 11) or in lieu of using a multiplicityof the foundation members 8 I -may use a foundation strip (see Fig. 12),the same being provided with diagonal slots 7 arranged in spaced pairsat intervals longitudinal of the strip, so that one strip mayaccommodate several of the shingles 5. r

In my Patent No. 1,595,080, of August 10,

1926, I have shown how it is possible to pro-' vide diagonal slots suchas 7 or"? in a member such as 8, or a strip such as 9, so as to receivethe corners of the shingle 5 in building up a roof covering.

The present invention, or at least that part above described, involvesthe same principle but distinguishes from the same in that in this caseI have suggested the use of inter-.

locking tabs such as 6.

Instead of using foundation members or foundation strips I may cutdiagonal slots 7 in the body of the shingles 5, so that the tabs 6 ofeach shingle may engage the slots 7* of each pair of shingles and thusbuild up a shingle roof covering, as illustrated in Figure 4. In thisembodiment I would do away with the foundation members 8 or foundationstrips 9.

When theshingle strip is called for I may construct the same, as shownin Figure 3, of a strip 10 out along one edge to simulate shinglemembers as at 11, and with the corners of.

the shingle members folded back to make the interlocking tabs 6 the sameas in the case of single shingles, referred to with reference to Figure2. In laying a shingle strip the tabs 6 may interlock with openingssuch" as the slots or slits 7 in a foundation member, or else the slotsor slits 7 a in a foundation strip '9. For the most part, however, Iwould arrange slots or slits 7 'in spaced pairs in the body of theshingle strip 10, so that by overlapping a ners thus provided may beturned into a pair of interlocking tabs 14 (see Figure 6). This pair oftabs would be best adapted for the edge of an adjacent and underlyingshingle rather than with slots, as heretofore referred to, although thisdoes not mean that it cannot be used in combination with slots.

The shingle 15 in Figure 7 may be cut so as to leave projections 16 ofadjacent corners, which may be later turned back as tabs 17-, as shownin Figure 8.

The shingle member 18, Figure 9, may be made with opposed projections,with the projections later turned back to make interlocking tabs 19.

s shown in Figure 10 the foundation member 22 is made with spacedparallel slots or slits 23, as compared to the diagonal slots 7 inFigure 11. These parallel spaced slots 23 are made to accommodate thoseinterlocking tabs illustrated as at 19 in the shingle member 18.

To accommodate the tabs 17 in the shingle member 15 to a slottedfoundation member,

the foundation strip slots would naturally be arranged to correspond tothe relative spaced relation of the tab 17 and this same principleapplies to other tab forms.

From the above it will be seen that the feature of the invention residesin interlocking a shingle strip or shingle member with an adjacentshingle member, or foundation member or foundation strip, by providingtabs on the overlapping shingle member or shingle strips which areadapted to interlock with slots in an underlying shingle member orshingle strip or foundation strip, or else interlock with the edge of anunderlying shingle member or shingle strip.

For the sake of convenience in defining the invention by the subjoinedclaims I will refer to the foundation members or foundation strips, andthe underlying shingle members or shingle strips as underlying members,as in reality they are such when the roof is covered with materialembraced by this invention. This is true even though the overlyingmembers become underlying'members when the roof is built up inhorizontal rows of spaced shingles.

I claim;

1. Shingles composed of flexible material, having in their body portionsa pair of slots spaced from opposite edges, and a pair of retrovertedtabs adapted to engage the slots of underlying shingles when laid inover# lapping relation for positively locking the tab ends of eachoverlying course to prevent same from lifting from each underlyingcourse.

2. Shingles composed of flexible material, having in their body portionsa pair of elongated slots spaced from opposite edges, and
